To select state or timing analysis
The HP E2456A preprocessor interface uses the same connections and
configuration for both state and timing analysis. The only difference is that
you choose Timing as the Type in the module Configuration menu of your
logic analyzer. See "To set up the preprocessor interface for timing" later in
this chapter and also Chapter 3 for line loading and timing skew (if any)
information.
The terminated (2X20) P4 connector provides delayed versions of ~UDS and
~LDS. For correct timing information on these signals, use the unterminated
(2X10) P7 connector with either a termination adapter (HP 01650-63203) or the
General Purpose (GP) probes supplied with your logic analyzer.
